Conector retractil en frio separable Campo tecnicoRetractable cold connector separable Technical field
La presente invencion se refiere a un sistema de terminacion de cable retractil en frio.The present invention relates to a cold retractable cable termination system.
AntecedentesBackground
Un sistema de terminacion de cable normalmente incluye un cable terminado con un terminal metalico (es decir, un conector de cable), insertandose el conector de cable y la parte extrema del cable en el alojamiento de un dispositivo de conexion, estando el conector de cable conectado a un dispositivo de acoplamiento dentro de los confines del alojamiento. El alojamiento ha de formar un cierre hermetico alrededor de la parte extrema del cable para evitar la contaminacion o la corrosion de la conexion. Un problema de los sistemas de terminacion de cable es que hay que adaptar el diametro interior del alojamiento al diametro del cable. Los tamanos de cable varian, por lo que resulta necesario tener o bien varios dispositivos de conexion de distintos tamanos, estando cada uno disenado para ajustarse perfectamente al diametro de cada cable particular, o bien varios adaptadores de distintos grosores, permitiendo cada adaptador que el alojamiento se adapte a un cable de un cierto diametro. Estas soluciones son costosas porque requieren un gran numero de dispositivos de conexion o de adaptadores para poder adaptarse a una gama completa de cables.A cable termination system usually includes a cable terminated with a metal terminal (i.e. a cable connector), the cable connector and the end of the cable being inserted into the housing of a connection device, the cable connector being connected to a coupling device within the confines of the housing. The housing must form a tight seal around the end of the cable to prevent contamination or corrosion of the connection. A problem with cable termination systems is that the inner diameter of the housing must be adapted to the diameter of the cable. The cable sizes vary, so it is necessary to have several connection devices of different sizes, each one being designed to fit perfectly to the diameter of each particular cable, or several adapters of different thicknesses, allowing each adapter to accommodate suits a cable of a certain diameter. These solutions are expensive because they require a large number of connection devices or adapters to be able to adapt to a full range of cables.
Otra solucion conocida consiste en proporcionar un alojamiento retractil en frio que puede expandirse a lo largo de casi toda su longitud para admitir cables que tengan una variedad de diametros. Cuando se emplea un alojamiento retractil en frio, se coloca un nucleo de soporte amovible dentro de una parte del alojamiento. El nucleo de soporte amovible tiene un diametro exterior que es mayor que el diametro interior de la parte de alojamiento cuando esta en estado relajado. En su estado expandido, el nucleo de soporte amovible sujeta el alojamiento hasta que el extremo de cable y el terminal se insertan en el alojamiento. A continuacion, se saca el nucleo, lo cual permite que el alojamiento retractil en frio se encoja alrededor del cable y lo apriete.Another known solution is to provide a cold retractable housing that can be expanded along almost its entire length to accommodate cables having a variety of diameters. When a cold retractable housing is used, a removable support core is placed inside a part of the housing. The removable support core has an outer diameter that is larger than the inner diameter of the housing part when it is in a relaxed state. In its expanded state, the removable support core holds the housing until the cable end and the terminal are inserted into the housing. The core is then removed, which allows the cold shrink housing to shrink around the cable and tighten it.
Un problema del sistema de terminacion de cable retractil en frio es que el extremo del nucleo de soporte amovible que esta colocado dentro del alojamiento no puede soportar la excesiva presion a la que le somete el alojamiento expandido, por lo que a menudo colapsara. Existen referencias en la tecnica anterior que han intentado abordar este problema mediante el refuerzo de los extremos del nucleo de soporte amovible.A problem with the cold shrink cable termination system is that the end of the removable support core that is placed inside the housing cannot withstand the excessive pressure to which the expanded housing is subjected, so it will often collapse. There are references in the prior art that have attempted to address this problem by reinforcing the ends of the removable support core.
WO 2009/035859 A1, US-2008/0156528 A1 y US-2005/0227522 A1 son ejemplos de referencias de la tecnica anterior.WO 2009/035859 A1, US-2008/0156528 A1 and US-2005/0227522 A1 are examples of prior art references.
SumarioSummary
La presente invencion pretende tratar el tema del colapso del nucleo provocado por la presion excesiva ejercida por un alojamiento expandido. Sin embargo, a diferencia de las soluciones de la tecnica anterior, la presente invencion se concentra en el alojamiento en vez de en el nucleo. La presente invencion proporciona un articulo tal y como el que se expone en la reivindicacion 1. En las reivindicaciones dependientes se enumeran caracteristicas preferidas.The present invention seeks to address the issue of core collapse caused by excessive pressure exerted by an expanded housing. However, unlike the prior art solutions, the present invention concentrates on the housing rather than the core. The present invention provides an article as set forth in claim 1. Preferred features are listed in the dependent claims.
La presente invencion presenta un articulo novedoso que comprende un alojamiento retractil en frio que tiene una primera camara que se interseca con una segunda camara, teniendo la primera camara una forma generalmente cilindrica con una parte superior lo mas proxima a la segunda camara, teniendo la parte superior un diametro superior al diametro del resto de la primera camara.The present invention presents a novel article comprising a cold retractable housing that has a first chamber that intersects with a second chamber, the first chamber having a generally cylindrical shape with an upper part closest to the second chamber, the part having superior a diameter superior to the diameter of the rest of the first chamber.
Una ventaja de al menos una realizacion de la presente invencion es que reduce la cantidad de presion que se ejerce sobre un extremo del nucleo de soporte retractil en frio insertado lo mas adentro en un alojamiento de dispositivo de conexion, reduciendose asi la probabilidad de que colapse el nucleo.An advantage of at least one embodiment of the present invention is that it reduces the amount of pressure exerted on one end of the cold retractable support core inserted deeper inside a connection device housing, thereby reducing the likelihood of collapse the nucleus.
Otra ventaja de al menos una realizacion de la presente invencion es que la capa semiconductora que esta en el interior de la primera camara del dispositivo de conexion esta en contacto estrecho con el conector de cable.Another advantage of at least one embodiment of the present invention is that the semiconductor layer inside the first chamber of the connection device is in close contact with the cable connector.
Una ventaja de al menos una realizacion de la presente invencion es que la capa semiconductora exterior proporciona una masa integrada porque hace contacto con la capa de masa metalica del cable.An advantage of at least one embodiment of the present invention is that the outer semiconductor layer provides an integrated mass because it makes contact with the metallic mass layer of the cable.
Una ventaja de al menos una realizacion de la presente invencion es que el dispositivo de conexion retractil en frio hace que sea innecesario un adaptador de cable. Esto elimina una interfaz electrica, que podria fallar.An advantage of at least one embodiment of the present invention is that the cold retractable connection device makes a cable adapter unnecessary. This eliminates an electrical interface, which could fail.

Los dibujos adjuntos muestran, a modo de ilustracion, realizaciones especificas en las que puede ponerse en practica la invencion. Cabe entenderse que pueden utilizarse otras realizaciones y hacerse cambios estructurales o logicos sin salirse del alcance de la presente invencion. Por lo tanto, la siguiente descripcion detallada no ha de tomarse en un sentido limitativo, y el alcance de la invencion viene definida por las reivindicaciones adjuntas.In the following detailed description of the preferred embodiments reference is made to the accompanying drawings that are part of the present specification. The attached drawings show, by way of illustration, specific embodiments in which the invention can be practiced. It is understood that other embodiments can be used and structural or logical changes made without departing from the scope of the present invention. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the invention is defined by the appended claims.
En la figura 1 se muestra un conjunto 20 de cable de alimentacion estandar que incluye un conector 22 de cable sujeto a un cable 24. El cable 24 incluye un conductor 26 de cable que esta concentricamente rodeado por un aislamiento 28 de cable, una pantalla 30 de aislamiento de cable, una masa 32 metalica de cable y una cubierta 34 de cable. Para formar el conjunto 20 de cable, hay que retirar cada uno del aislamiento 28 de cable, la pantalla 30 de aislamiento de cable, la masa 32 metalica de cable y la cubierta 34 de cable de un extremo del cable 24 para dejar expuesta una parte de la capa subyacente, hasta un conductor 26 de cable. El conector 22 de cable se sujeta entonces a la parte expuesta del conductor de cable 26 por cualquier medio adecuado, normalmente por engaste.A standard power cable assembly 20 is shown in Fig. 1 that includes a cable connector 22 attached to a cable 24. The cable 24 includes a cable conductor 26 that is concentrically surrounded by a cable insulation 28, a screen 30 of cable insulation, a metal cable mass 32 and a cable cover 34. To form the cable assembly 20, each of the cable insulation 28, the cable insulation screen 30, the metal cable mass 32 and the cable cover 34 of one end of the cable 24 must be removed to expose a portion from the underlying layer, to a cable conductor 26. The cable connector 22 is then attached to the exposed part of the cable conductor 26 by any suitable means, usually by crimping.
En la figura 2 se muestra un dispositivo 100 de conexion que incluye un alojamiento 102 que define de manera general una primera camara 104 y una segunda camara 106. La primera camara 104 y la segunda camara 106 se intersecan, de manera que el interior de la primera camara 104 esta en comunicacion con el interior de la segunda camara 106. Las primera y segunda camaras 104 y 106 pueden intersecarse y formar una forma general de T, tal y como se muestra en la figura 2, o una forma general de L (no mostrada). La primera camara 104 incluye ademas una parte superior 108 que esta situada lo mas proxima a la segunda camara 106. Tal y como puede observarse en la figura 2, los diametros interior y exterior de la parte superior 108 de la camara 104 son mayores que los diametros interior y exterior del resto de la primera camara 104. El alojamiento 102 puede incluir ademas una capa 110 semiconductora exterior y una capa 112 aislante intermedia, estando la pared interior de la primera camara 104 al menos parcialmente cubierta por una capa 114 semiconductora interior.A connection device 100 is shown in Fig. 2 which includes a housing 102 which generally defines a first chamber 104 and a second chamber 106. The first chamber 104 and the second chamber 106 intersect, so that the interior of the First chamber 104 is in communication with the interior of the second chamber 106. The first and second cameras 104 and 106 may intersect and form a general form of T, as shown in Figure 2, or a general form of L ( not shown) The first chamber 104 also includes an upper part 108 which is located closest to the second chamber 106. As can be seen in Figure 2, the inner and outer diameters of the upper part 108 of the chamber 104 are larger than the inner and outer diameters of the rest of the first chamber 104. The housing 102 may further include an outer semiconductor layer 110 and an intermediate insulating layer 112, the inner wall of the first chamber 104 being at least partially covered by an inner semiconductor layer 114.
El alojamiento 102 puede estar hecho de cualquier material apto para aplicaciones de retraccion en frio. Los mas adecuados son materiales tales como un material de caucho muy elastico que tenga poca capacidad de deformacion permanente, tal como un monomero de etileno-propileno-dieno (EPDM), una silicona elastomerica o un hibrido de los mismos. Los materiales semiconductores y aislantes pueden estar hechos de los mismos o de diferentes tipos de materiales. Los materiales semiconductores y aislantes pueden tener grados de conductividad y de aislamiento diferentes en funcion de las propiedades intrinsecas de los materiales empleados o en funcion de los aditivos que se hayan anadido a los materiales.The housing 102 may be made of any material suitable for cold retraction applications. The most suitable are materials such as a very elastic rubber material that has little permanent deformability, such as an ethylene-propylene-diene monomer (EPDM), an elastomeric silicone or a hybrid thereof. Semiconductor and insulating materials can be made of the same or different types of materials. Semiconductor and insulating materials may have different degrees of conductivity and insulation depending on the intrinsic properties of the materials used or depending on the additives that have been added to the materials.
Para permitir que el conjunto 20 de cable se inserte en la primera camara 104 del dispositivo 100 de conexion, primero se carga un nucleo 200 de soporte de soporte amovible en la primera camara 104, tal y como se ilustra en la figura 3. Una vez cargado, el nucleo 200 de soporte de soporte amovible normalmente se extiende desde el extremo de la parte superior 108 mas proxima a la segunda camara 106 hasta mas alla del extremo abierto 109 de la primera camara 104 por el que se inserta el conjunto 20 de cable. Cuando se carga en la primera camara 104, el nucleo 200 de soporte de soporte amovible expande radialmente la primera camara 104 hasta que alcanza un diametro interior superior al diametro exterior de la parte mas grande del conjunto 20 de cable que se insertara en la primera camara 104.To allow the cable assembly 20 to be inserted into the first chamber 104 of the connection device 100, a removable support support core 200 is first loaded into the first chamber 104, as illustrated in Figure 3. Once loaded, the removable support support core 200 normally extends from the end of the upper part 108 closest to the second chamber 106 to beyond the open end 109 of the first chamber 104 through which the cable assembly 20 is inserted . When loaded in the first chamber 104, the removable support support core 200 radially expands the first chamber 104 until it reaches an inside diameter greater than the outside diameter of the largest part of the cable assembly 20 to be inserted into the first chamber 104.
El nucleo 200 de soporte de soporte amovible puede ser de cualquier material adecuado y estar en cualquier configuracion adecuada, pero normalmente consiste en una cinta de nailon o de propileno extrudido que esta enrollada helicoidalmente. Para retirar el nucleo 200 de soporte de soporte amovible de la primera camara 104, el nucleo de soporte de soporte amovible se desenrolla tirando de una lengueta (no mostrada) que se extiende desde un extremo del nucleo 200 de soporte de soporte amovible y provoca la separacion del nucleo a lo largo de la linea de desgarro helicoidal. Preferiblemente, el nucleo 200 de soporte amovible se desenrolla empezando por el extremo en la parte superior 108 mas proxima a la segunda camara 106 y acabando por el extremo que se extiende mas alla del extremo abierto 109 de la primera camara 104. Desenrollar el nucleo 200 de soporte de soporte amovible de esta manera evita que el extremo abierto 109 de la primera camara 104 colapse prematuramente e impida la retirada del nucleo 200 de soporte de soporte amovible.The removable support support core 200 may be of any suitable material and be in any suitable configuration, but usually consists of an extruded nylon or propylene tape that is helically wound. To remove the removable support support core 200 from the first chamber 104, the removable support support core is unwound by pulling a tab (not shown) that extends from one end of the removable support support core 200 and causes the separation of the nucleus along the helical tear line. Preferably, the removable support core 200 is unwound starting at the end at the top 108 closest to the second chamber 106 and ending at the end that extends beyond the open end 109 of the first chamber 104. Unwind the core 200 The removable support support in this manner prevents the open end 109 of the first chamber 104 from prematurely collapsing and preventing the removal of the removable support support core 200.

Cuando un extremo de un nucleo de soporte de soporte amovible esta situado en el interior de una camara tal y como ocurre en la presente invencion, es posible que la presion ejercida por la camara expandida sobre el extremo del nucleo que esta en la camara haga que el extremo del nucleo de soporte de soporte amovible colapse. La presente invencion aborda este problema proporcionando una parte superior 108 de la primera camara que tiene unos diametros interior y exterior mayores que los del resto de la camara. Gracias a esta caracteristica, se requiere que la parte superior 108 de la primera camara se expanda menos que en dispositivos conectores de la tecnica anterior que no tienen esta caracteristica y, por tanto, se ejerce menos presion sobre el extremo del nucleo de soporte amovible que esta en el interior de la camara en comparacion con dispositivos conectores similares de la tecnica anterior.When one end of a removable support support core is located inside a chamber as in the present invention, it is possible that the pressure exerted by the expanded chamber on the end of the core in the chamber causes the end of the support core support removable collapse. The present invention addresses this problem by providing an upper portion 108 of the first chamber having inner and outer diameters larger than those of the rest of the chamber. Thanks to this feature, the upper part 108 of the first chamber is required to expand less than in prior art connector devices that do not have this feature and, therefore, less pressure is exerted on the end of the removable support core than It is inside the camera compared to similar connector devices of the prior art.
Preferiblemente, el diametro interior de la parte superior 108 de la primera camara 104 tiene un tamano tal en comparacion con el diametro exterior de un nucleo 200 de soporte amovible que se ha insertado en la primera camara 104 que el aumento maximo del diametro interior de la parte superior 108 cuando el nucleo 200 de soporte amovible se carga en la primera camara 104 es inferior al 100 %, mas preferiblemente, igual o inferior a aproximadamente el 20 % y superior al 0 %, del diametro interior cuando el nucleo 200 de soporte amovible esta ausente de la primera camara 104.Preferably, the inner diameter of the upper part 108 of the first chamber 104 has such a size compared to the outer diameter of a removable support core 200 that has been inserted into the first chamber 104 that the maximum increase of the inner diameter of the upper part 108 when the removable support core 200 is loaded in the first chamber 104 is less than 100%, more preferably, equal to or less than about 20% and greater than 0%, of the inner diameter when the removable support core 200 It is absent from the first chamber 104.
La diferencia en diametro interior de la parte superior 108 y el resto de la primera camara 104 normalmente hara que la parte superior 108 y el resto de la primera camara experimenten un aumento diferencial de diametro interior cuando se cargue un nucleo de soporte amovible en la primera camara. Es decir, se requerira que el diametro interior de la parte superior 108 aumente menos que el diametro interior del resto de la primera camara para admitir un nucleo 200 de soporte amovible. Esto es particularmente cierto cuando el nucleo 200 de soporte amovible tiene un diametro exterior constante, pero tambien puede ser cierto cuando el nucleo de soporte amovible tenga una forma escalonada o conica. Independientemente de la forma del nucleo 200 de soporte amovible, resulta deseable que el diametro exterior del nucleo 200 de soporte amovible sea mayor que los diametros interiores tanto de la parte superior como del resto de la primera camara en su estado relajado para que la superficie interior de la primera camara 104 ejerza al menos una cantidad de presion suficiente sobre el nucleo 200 de soporte amovible como para evitar que se salga de la primera camara 104. Si el diametro exterior del nucleo 200 de soporte amovible varia a lo largo de su longitud, tal y como sucede con un nucleo escalonado o conico, el diametro exterior de cada parte del nucleo 200 de soporte amovible es preferiblemente superior al diametro interior de la parte adyacente de la primera camara 104.The difference in inner diameter of the upper part 108 and the rest of the first chamber 104 will normally cause the upper part 108 and the rest of the first chamber to experience a differential increase in inner diameter when a removable support core is loaded in the first camera. That is, the inner diameter of the upper part 108 will be required to increase less than the inner diameter of the rest of the first chamber to admit a core 200 of removable support. This is particularly true when the removable support core 200 has a constant outside diameter, but it can also be true when the removable support core has a stepped or conical shape. Regardless of the shape of the removable support core 200, it is desirable that the outer diameter of the removable support core 200 be larger than the inner diameters of both the top and the rest of the first chamber in its relaxed state so that the inner surface of the first chamber 104 exerting at least a sufficient amount of pressure on the removable support core 200 to prevent it from leaving the first chamber 104. If the outer diameter of the removable support core 200 varies along its length, as with a stepped or conical core, the outside diameter of each part of the removable support core 200 is preferably greater than the inside diameter of the adjacent part of the first chamber 104.
Preferiblemente, el aumento maximo del diametro interior de la parte superior cuando se carga un nucleo de soporte amovible en la primera camara esta entre aproximadamente el 100 % y aproximadamente, pero superior al, 0 % del diametro interior cuando el nucleo de soporte amovible esta ausente de la primera camara, y el aumento maximo del diametro interior del resto de la primera camara cuando se carga un nucleo de soporte amovible en la primera camara esta entre aproximadamente el 150 % y aproximadamente el 300 % del diametro interior cuando el nucleo de soporte amovible esta ausente de la primera camara.Preferably, the maximum increase of the inner diameter of the upper part when a removable support core is loaded in the first chamber is between about 100% and about, but greater than, 0% of the inner diameter when the removable support core is absent. of the first chamber, and the maximum increase of the inner diameter of the rest of the first chamber when a removable support core is loaded in the first chamber is between about 150% and about 300% of the inner diameter when the removable support core It is absent from the first chamber.
Una vez que se ha cargado el nucleo de soporte amovible en la primera camara 104, el conjunto 20 de cable puede insertarse en la primera camara 104. Normalmente, el conector 22 de cable incluira una abertura 23 en su extremo libre. El extremo libre se coloca en la interseccion entre las primera y segunda camaras 104, 106, residiendo el resto del conector de cable en la parte superior, y una parte adyacente de camara, de la primera camara 104. Una vez que se ha colocado correctamente el conjunto de cable, puede insertarse una espiga (no mostrada) por la abertura 23 y pueden insertarse uno o mas dispositivos 42 de acoplamiento en la segunda camara 106 y sujetarse al conector 22 de cable, o mantenerse en su sitio contra el, por la espiga. Tal y como se ha descrito anteriormente, el nucleo 200 de soporte amovible puede entonces retirarse para provocar que la primera camara 104 se contraiga y forme un cierre hermetico alrededor del conjunto 20 de cable.Once the removable support core has been loaded into the first chamber 104, the cable assembly 20 can be inserted into the first chamber 104. Normally, the cable connector 22 will include an opening 23 at its free end. The free end is placed at the intersection between the first and second cameras 104, 106, the rest of the cable connector residing at the top, and an adjacent chamber part, of the first camera 104. Once it has been correctly placed the cable assembly, a pin (not shown) can be inserted through the opening 23 and one or more coupling devices 42 can be inserted in the second chamber 106 and secured to the cable connector 22, or held in place against it, by the spike. As described above, the removable support core 200 can then be removed to cause the first chamber 104 to contract and form a seal around the cable assembly 20.
Tal y como se muestra en la figura 4, cuando el dispositivo de conexion se ha ensamblado completamente, la capa 114 semiconductora interior sobre la pared interior de la primera camara 104 del alojamiento 102 esta en contacto estrecho con el conector 22 de cable del conjunto 20 de cable. Preferiblemente, la capa 114 semiconductora interior tambien esta en contacto estrecho con el aislamiento 28 de cable del conjunto 20 de cable. Una parte de la pared interior de la primera camara 104 esta formada por la capa 112 aislante intermedia. Preferiblemente, esta parte esta en contacto estrecho con el aislamiento 28 de cable. Una parte de la pared interior de la primera camara 104 esta formada por la capa 110 semiconductora exterior. Preferiblemente, esta parte esta en contacto estrecho con la pantalla 30 de aislamiento de cable, y normalmente tambien esta en contacto estrecho con la masa 32 metalica de cable, que puede ser una capa de alambre o de cinta. Preferiblemente, la parte de la pared interior de la primera camara 104 que esta formada por la capa 110 semiconductora exterior tambien esta en contacto estrecho con una parte de la cubierta 34 de cable para evitar la entrada de contaminantes y/o de humedad en la primera camara 104.As shown in Figure 4, when the connection device has been completely assembled, the inner semiconductor layer 114 on the inner wall of the first chamber 104 of the housing 102 is in close contact with the cable connector 22 of the assembly 20 of cable. Preferably, the inner semiconductor layer 114 is also in close contact with the cable insulation 28 of the cable assembly 20. A part of the inner wall of the first chamber 104 is formed by the intermediate insulating layer 112. Preferably, this part is in close contact with the cable insulation 28. A part of the inner wall of the first chamber 104 is formed by the outer semiconductor layer 110.
